the following system, we want it to have infinite many solutions. But it only happens when \( h, k \) take certain values. Find the value for \( h \) and the value for \( k \) so that the system has infinite many solutions. \[ \begin{array}{l} 6 x+6 y-5 z=-4 \\ 6 x+5 y-4 z=5 \\ 30 x+28 y+h z=k \\ \end{array} \] When \( k=\quad \) and \( h=\quad \) the system has infinite many solutions.
